The drug helps improve breathing and lowers pulmonary capillary wedge pressure.
2.
See also pulmonary wedge pressure and ventricular pressure.
3.
High cardiac index and pulmonary capillary wedge pressures, however, may lead to false positives by this standard.
4.
A cannula or catheter inserted into an artery may be used to measure pulse pressure or pulmonary wedge pressures.
5.
Once the catheter is in the hepatic vein, a wedge pressure is obtained to calculate the pressure gradient in the liver.
6.
Part of the procedure, a hepatic vein wedge pressure is measured with the assumption of no pressure drop across the liver yielding portal vein pressure.
7.
It has also been used to diagnose severity of left ventricular failure and mitral stenosis, given that elevated pulmonary capillary wedge pressure strongly suggests left ventricular output.
8.
Pulmonary congestion is typically not seen because equalization of diastolic pressures constrains the pulmonary capillary wedge pressure to the intra-pericardial pressure ( and all other diastolic pressures ).
9.
In a prospective randomized study involving 86 patients who underwent right and left cardiac catheterization, the abdominojugular test was shown to correlate best with the pulmonary arterial wedge pressure.
10.
The abdominojugular test, when done in a standardized fashion, correlates best with the pulmonary arterial wedge pressure, and therefore, is probably a reflection of an increased central blood volume.
